"'function' object has no attribute '_reset'" in pwndbg/pwndbg/color/syntax_highlight.py

[sci-42ver]

Description

using latest dev branch, with set syntax-highlight-style solarized-light param, above error will be thrown

$ gdb ~/matrix-matrix-multiply/build/src/dgemm -ex 'start' -ex ''

AttributeError: 'function' object has no attribute '_reset'
/home/czg/.gdbinit:19: Error in sourced command file:
Error occurred in Python: 'function' object has no attribute '_reset'

when I read $ git log -p pwndbg/commands/context.py I found nothing about _reset, but the error only exists after I upgrade python from 3.10 to 3.11.3 and pwndbg recently.

[disconnect3d]

The _reset was a method to clear a cache for a given function; this method name was changed with recent caching rewrite.

[disconnect3d]

This should be changed as:

- get_highlight_source._reset()
+ get_highlight_source.cache.clear()

[disconnect3d]

Fwiw there are no other instances of this issue (after fixing this one):

dc@dev-vps:~/pwndbg$ rg '\._reset'
dc@dev-vps:~/pwndbg$

[disconnect3d]

This has been fixed in #1757
